CLA 45 amg c118 throttle body location

Hello, I have a 2021 CLA45 AMG, and I’m having an issue with the RPM when the car is idling. I’ve already cleaned the MAP sensor located next to the turbo, which was dirty, and the one at the front of the engine. However, I’m having trouble finding the throttle body on my car. It’s usually easy to locate the throttle body on any car, but on this one, it’s different. If someone knows where it is, that would be great. I’ve attached a picture of my engine for reference.

Follow the intake to throttle body. Assuming it is out of warranty?

Usually on Mercedes Benz vehicles the throttle body is integral to the plastic engine cover . It looks like your CLA late model has a different design more like an American vehicle. The throttle body is located where those two silver o rings are . But I think you have a different problem such as bad throttle position sensor I don't think the vacuum leaks would cause such described high rpms better get it to your local Mercedes Benz service station
